Tell me about an interesting task from your past experience. What did you do at the company?

In one of the companies, I participated in developing a high-load service in Go for real-time data stream processing. My task was to optimize performance and reduce latency in message processing from queues. To achieve this, I implemented a goroutine pool with load control and used channels for efficient synchronization. I also refactored the code to improve readability and maintainability, and wrote unit and integration tests to enhance system reliability.
